Hi Ondřej, It appears that this patch assumes a normal PECL extension and I'm not sure sass is one?
The build eventually fails with: cp -a undefined build-7.1 cp: cannot stat 'undefined': No such file or directory /usr/share/dh-php/pkg-pecl.mk:60: recipe for target 'configure-7.1-stamp' failed make[1]: *** [configure-7.1-stamp] Error 1 from dh-php.mk: configure-%-stamp: cp -a $(PECL_SOURCE_$(*)) $(SOURCE_DIR) $(foreach ver,$(DH_PHP_VERSIONS),$(eval PECL_SOURCE_$(ver) := $(if $(PACKAGE_XML_$(ver)),$(shell xml2 < $(PACKAGE_XML_$(ver)) | sed -ne "s,^/package/name=,,p")-$(shell xml2 < $(PACKAGE_XML_$(ver)) | sed -ne "s,^/package/version/release=,,p"),undefined))) Since there is no package.xml, this results in undefined? In a quick look through pkg-pecl.mk, I'm not seeing an obvious override for this case? Also, should the above resulting in undefined be a fatal error since the build is going to eventually fail (and maybe with a better message: "unable to determine PECL source version from package.xml"?)
